AI Technical Summary

Technical Problem

Conventional 3D measurement technologies using handheld cameras lack intuitive guidance for users, leading to potential inaccuracies due to subjective photography procedures, especially for less skilled users, which can reduce the accuracy of 3D measurements.

Method used

A photographing device equipped with a display unit and processor that analyzes captured images to determine if work support is needed, providing guidance through messages to improve photography based on blur, point cloud density, feature points, sudden movements, and elapsed time, ensuring accurate 3D measurement.

Benefits of technology

Users receive clear guidance to improve their photography, maintaining or enhancing the accuracy of 3D measurements regardless of their proficiency level, by addressing issues like blur, point cloud density, and camera movement.

Abstract

To provide a photographing device, a photographing operation support method, and a photographing operation support program that guide a point to be immediately improved in relation to a user's photographing operations in an easy-to-understand manner to the user performing the photographing operations, and thereby allow the user to execute the photographing operations according to an appropriate method regardless of the skill level of the user, or the like.SOLUTION: In order to perform three-dimensional measurement processing of generating three-dimensional space information of a measurement target place on the basis of a photographed image of the measurement target place, a photographing device that photographs the measurement target place, displays, on a display, operation support information related to photographing operations performed by a user photographing the measurement target place while moving in the measurement target place, especially, determines the necessity of operation support for improving the state of the user's photographing operations on the basis of the state of the photographed image, specifically, the state of occurrence of blur in the photographed image, the state of generation of point groups generated as a measurement result in the three-dimensional measurement processing, and the state of extraction of feature points extracted from the photographed image, and when the operation support is required, displays a warning message for encouraging the user to take an action to improve the state of the user's photographing operations as the operation support information.SELECTED DRAWING: Figure 2
